Narrowleaf Milkweed, Narrow Leaf Milkweed, Mexican Whorled Milkweed
Asclepias fascicularis (Narrowleaf Milkweed) is a flowering perennial boasting attractive clusters, 4-5 in. across (10-12 cm), of lavender and white, starry flowers from early summer to fall. Flowers are a great source of nectar for bees, butterflies, hummingbirds, and other pollinating insects. The blooms occur on upright, thin stems clad with long, narrow, pointed leaves. They give way to smooth seed pods in the fall, which look great in dried flower arrangements. When the seed pods open, they reveal seeds with long, silvery-white, silky hairs. Adaptable to high or low water, heat, and all types of soils (including clay), this is one of the easiest and fastest milkweeds to establish – A great choice for the flower garden and for natural settings. Milkweed plants are critical to monarch butterflies‘ survival, whose population in North America has plummeted by 90% in the last 20 years. By planting milkweed in your own garden, you can help reverse the fortune of these beautiful insects!
